MIL in hospice care. Nurse keeps calling

My husband hasn't spoken to his mother since he was 20 and hasn't been in person with her since he was 16. He ran away. A nurse called. She's in hospice care and the nurse says she wants to see my husband. That she cries every night wanting to see her only son. My husband has more or less said she can die and die knowing she was never forgiven. But the nurse keeps calling. It got to the point my husband cussed her out the last time she called him and the mom somehow was able to get my number(probably from SIL) and now nurse is calling me begging me to talk to him because all she wants is to see her son before she goes. So now I'm dealing with her blowing my phone up

@Shamika no. That would probably get me left. There is a lot of baggage there. He wants nothing to do with her. I respect that and even suggesting that would be disrespectful to him and his trauma.
